COTTON-GIN.

SPECIFICATION forming part Of Letters Patent No. 457g690, dated August11, 1891.

Application filed December 29, 1890. Serial No. 376,096. (No model.)

T0 aZZ whom it may concern:

Be it known that I, CORNELIUS YOUNG, a citizen of the United States, anda resident of Selma, in the county of Dallas and State of Alabama, haveinvented certain new and use ful Improvements in Cotton-Grins; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

Figures 1 and 2 of the drawings are op posite side elevations. Fig. 3 isa vertical longitudinal section thereof, and Fig. 4is a plan viewthereof with the cover removed.

This invention relates to gins for separating seed, dirt, and foreignmatter from cotton in the condition in which it comes from the field.

The object is to provide a device of this character which will card andstraighten'the fiber without cutting or napping, which will morethoroughlyremove all lint from the seed than heretofore, and which willdo the entire work more rapidly and effectually than the devices now inuse for this purpose.

With these objects in view the invention consists in the novelconstruction and combination of the various parts, as hereinafter fullydescribed.

In carrying out my invention I employ a suitable frame or closure(designated by the letter Z in the accompanying drawings illustratingthe invention.) A represents a drum horizontallyjournaledin said frameand provided with a covering of card-clothin g, having short strongsteel teeth, sharpened and set at an angle, so that they will pick upand These teeth are so closely set that when the drum is in operation aseed cannot be forced between them. Instead 'of the card-clothing I mayemploy any well-known equivalent. This drum or brush is driven by themain drivingpulley a on its shaft, which is connected with suitablepower for the purpose. B represents a similar drum journaled in the samevertical plane and separated by but a short space from brush A. Thisdrum is also provided alent similar to that on A, but with the exceptionthat the teeth are inclined in the opposite direction and arevpreferably somewhat longer and disposed in rows sufficiently spaced fromeach other to allowa cotton-seed to pass between them. The shaft of thisdrum carries a pulley b, which is driven by a belt from 1 a pulley Ct onthe shaft of brush A.

O represents a drum of smaller size than drums A and B and journaledslightly to the rear of and intermediate of the centers of said drums,coming more nearly in contact with A than with B, as shown. This drum 0is covered with very fine steel-wire card clothing or bristles, and isdriven by apulley con its shaft by a belt from a pulley b on the shaftof drum B.

D is a fourth drum journaled in the same horizontal plane with. and atthe rear of the drum ]3 and preferably somewhat smaller.- This drum isprovided with a card-covering similar to that of drum or brush 0, and isdriven by means of a pulley cl on its shaft, driven by abelt from apulley e on the shaft of a drum E, next to be described.

Erepresents a drum of large size journaled in the same horizontal planeas the drum or brush A, but forward thereof. This drum E is covered withsteel-wire card-clothing or bristles of suitable length and set in rowsspaced apart, as shown. The shaft of this drum has a pulley e, driven bya cross-belt from a pulley b" on the shaft of brush B.

F represents the feed-hopper, having at its lower portion the inclinedscreen F, held in grooves or Ways in the side pieces f and adjustabletherein by means of the plates pone on each side-toward or away from thelower portion of brush A, to the rear of which said hopper and screenare located. This screen is preferably'of coarse wire-cloth, the meshesof which, however, are not sufficiently large to admit of the passagetherethrough of a seed in the position in which said screen is held.

The seed-cotton is fedinto the hopper either by hand or by means of afeeder. It is there taken up by the brush A and carried to C. The fibersof the cotton will to a great extent with a covering of card-clothing orits equivbe driven into the card-teeth of A and a portion of the seedbroken off and thrown back into the hopper, to be again taken up by thesaid brush and beaten back until freed from its fiber, when it will dropout through openings between brush A and the forward edge of the screen.The seed not broken off by brush Owill remain on top of brush A, wherethey will be taken by B, the teeth of which stand in the reversedirection, as before stated. This brush will remove more of the fiber,such seed and fiber being carried upward and backward to brush D, thencedown onto screen F, where it will be again taken by brush A and theoperation repeated. The seed, however, will rarely pass brush 0 morethan once before being thoroughly freed from fiber; but as long as anyfiber adheres to the seed they will continue to be taken up by A. Thelint-cotton which has been thus freed from its seed and a large portionof its dirt will be carried by brush A over to brush E, where it will beswept off by the bristles or steel card-clothing, and after beingtreated by said brush will be blown through the flue H into thecondenser or lint-room.

I represents a mote board or screen located under the brush E, throughwhich the heavier dirt remaining in the lint will fall. It is providedthat brush 0 shall receive draft from below through an opening in thecase or closure between brush A and mote-board I, as shown.

K K represent openings in the casinglor closure to allow the escape ofsmall accumulations of lint-cotton which may form between the heads ofthe drums or brushes B and D and the inside of the frame or casing.

L represents a circular opening in the easing for the purpose of givingadditional draft to the machine, and this opening is provided with asliding door L, by means of which the size of the opening and theconsequent draft may be regulated.

Instead of the drive-belts herein shown and described I may, if desired,use sprocket-gear, pinions, or any suitable gearing.

Having thus described this invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the casingor closure, of the card-brushes A andB, oneabove the other, the brush 0, intermediate of and to the rear ofsaid brushes, the brush D at the rear of brush B, and the lint-brush infront of brush A, said brushes being of different sizes and having theircard teeth or bristles of different sizes and differently disposed andhaving their shafts journaled in said casing and intergeared,substantially as specified.

2. In a cotton-gin, the combination, with the frame or casing having thehopper, the discharge-chute, the draft openings, and the screens, of thecard-brushes A and B, one above the other, the brush 0, intermediate ofand to the rear of brushes A and B, the brush D at the rear of brush B,and the lint-brush in front of brush A, said brushes being of differentsizes and having their card teeth or bristles of different sizes anddifferently disposed and having their shafts journaled and intergearedin said frame, substantially as specified.

3. In a cotton-gin, the combination, with the frame or casing, of thecard-brushes or drums A and B, one above the other, the brush 0,intermediate of and to the rear of brushes A and B. the brush D at therear of brush B, and the lint-brush in front of brush A, said brushes ordrums being of different sizes and having their card teeth or bristlesof difierent sizes and differently disposed, substantially as specified.

4. The cotton-gin comprising, in combination with the frame or closurehaving the draft and discharge opening and hopper, the brush A havingits bristles or teeth set closely together, brush B above brush A andhaving its bristles or teeth farther apart and arranged in rows,brushesO and D, one above the other and of difierent sizes, journaled atthe rear of the two first-named brushes and suitably disposed withrelation thereto, and the lint brush or card E, arranged as described,said brushes being intergeared and driven by' drive-gear on the shaft ofbrush A, substantially as described.

In testimony whereof I affix my signatu re in presence of two witnesses.
